Your favorite computer program (after being converted to MIPS assembly code, then to machine code) results in 2.5e8 instructions. Consider the three different CPUs and their clock rates and CPIs and determine how much time it would take each of them to execute this program. Rick Sanchez’s computer with a clock rate 7.99 Hz (hertz, not gigahertz) and a CPI of 1.1.

Suppose we have two implementations of the same instruction set architecture. Computer A has a clock cycle time of 210 ps and a CPI of 2.2 for some programs, and computer B has a clock cycle time of 460 ps and a CPI of 1.3 for the same program. Which computer is faster for this program and by how much? Please and thank you

Calculate the CPU execution time (expressed in milliseconds) of a program with 10 million instructions on a 2.5 GHz CPU with the following basic instruction-type breakdowns and CPIs: Arithmetic: 60%, CPI = 2 Load & Store (assuming perfect caches): 25%, CPI = 5 Branching: 15%, CPI = 3 In addition, you are told that the overall cache miss rate for instructions is 1%, the overall cache miss rate for data is 3%, and the cache miss penalty is 100 cycles. You can ignore the hit time (consider it zero).

Please compute for the CPU utilization:
